LIFTING AND RETAINING DEVICE FOR SLIDING WINDOWS.

Application. filed April 14, 1922. Serial No. 552,548.

This invention relates ,to an improved lifting and retaining device for sliding win- ,dows and it has'to do, more particularly, with a device for lifting sliding windows of the type generally used in automob le bodies and for retaining said windows 1n their closed position.

The principal object of my invention 1s to provide a simple and inexpensive dev ce which may be readily attached to the window sash and by means of which the sash may be retained in its lifted or closed-position and which also furnishes means for the attachment of a lifting strap to the window.

A further object of my invention is to provide means for fastening a lifting strap to a sliding Window and means independent of the strap for retaining the window in lifted or closed position, so that the lifting strap is relieved of all strain when the windowis closed. Y

Andther object of my invention is to provide a member which is hinged to the window and to which a lifting strap may be 2 connected, said member being provided with 'means adapted to be engaged by a stationary hook on the automobile body for retaining the window in closed position. Further objects, and objects relating t details and economies of operation and construction, will definitely appear from the detailed description to, follow. In one in,- stance, I accomplish the objects of my invention by the devices and means described in-the following specification. My invention is clearly defined and pointed out in the appended claims. A structure constitutinga preferred embodiment of my invention is illustrated in the accompanying drawing, forming a part of this speci c which: H

Fig. 1 is a'fragmentary view in side elevation showing a portion of an automobile my liftbody and a window provided with in and fastening device. I I'ig. 2 is a sectional view, taken on the line 2-2 of Fig. 1, and

Fig. 3 is a view of my device in front elevation.

In the drawing, the same reference numer- 5o als refer to the same/parts throughout the several views and the sectional View is taken looking in the direction of the arrows at the ends of the section line.

In general, my invention consists in providing amember which is movably secured to the window or to the window sash and which is adapted to engage over a stationary support therefor fixed on the automobile body, to retain the sliding window in its 60 upper or closed position. This member is also connected to the lifting strap by means of which the window is raised from and lowered into thewindow well of the body. In order to permit this member to clear-66 the hook in lowering the window into'and raising it from the well, I find it desirable to hinge said member to the window or window sash. a

Broadly speaking, and from the stand- 70 point of the object attained, the retaining device comprises a metallic fastening member carried by the window, a co-acting metallic fastening member carried \by the window ledge, one at least of which members .7 is relatively movable with respect to its support to engage and fasten upon the other, and means" for raising and lowering the window which bring the fastening members within operative range of each other. This 30 latter means is the flexible lifting strap.

In the accompanying drawing, I have shown a device embodying my invention employed for lifting and for retaining in raised position a sliding or drop window of the t pe commonl used in a closed automobi e body. Re erring to the numbered parts of these drawings, the'automo-' bile body, 10, has awindow' opening formed therein in any usual or desired manner, as, for example, by inturned flanges to which the finishing strip, 11, is secured. If desired, the strip, .11, may carry a weather strip, 12, at the lower edge of the window opening, which is adapted to engage the window. In the construction of the body, a window well, 13', is provided, into which the window'may be dropped with the details of structure of the window ing strap, 31, and

when it is desired to leave the window opening open. My invention is not concerned or the window openin but has to do, more particularly, with a evice for lifting the window from this window well and for retaining it in its upper position. The w ndow, 13,- slides from its upper position to its lower position in the window well and, as usual, the lower edge of the window is 051-- tioned in the metal channel, 14, with fe t or similar packing, 15,. interposed between the lass and the metal of the channel. The ifting and retaining device is preferably secured to this channel member. In the particular arrangement shown as an lllustrative embodiment of my1 invention, I have provided a plate, 21, w the base of the channel, 14, by welding or in an other suitable manner. Spaced hinge knuc les, 22 are formed at one edge of this plate. A plate, 23, is provided with hinge knuckles, 24, at brought into alinement with the knuckles, 22, the two parts being hinged together by the intle, 25, passed through the alined knuc les. This plate, 23, is provided with an opening, 26, to receive a retaining device, 18, carried by the body, to support the window in its upper position. The-upper edge portion of the plate, 23, engages around the lower reach, 28, of a loop, as indicated at 27. A lifting strap, 31, is looped around the upper reach, 29, of said loop, .as indicated at 30. The inner sides of t e window opening may be finished in any desired manner, as, for example, by the strips or moldings, 17 sists of a stamping, 16, secured to the body and provided with an upturned finger, 18, which extends towards the window and into position to be received through the opening, 26, in the plate, 23, when the window is raised into its upper or closed position. The upturned finger, 18, is accommodated in aspace, 20, formed by off-setting the finishing strips or moldings, 17, 19.

In practice, the operation of this device is very simple. In Fig. 2, the parts are shown in position for retaining the window in its u per or closed position. To lower the win ow the operator lifts onthe liftraises the plate, 23, from. engagement with the support, 18, swinging it, as he does so, toward the window about the bin e pintle, 25. This permits the plate, ear the support, 18, andthe window may then be lowered completely into the well, or it may be retained in any mediate position by fastening devices engaging the liftingstrap, 31, in accordance with present practice. To raise the window to the closedposition, the operator lifts on the lifting strap, 31, thus moving the window upwardly,in the ways provided thereich is secured to its lower edge, adapted to be and 19. The retaining device con' interfor. When its upper position is reached he swings the lifting strap, 31, and the hinged plate, 23, awa from the window and lowers the window s ightly so that the support, 18, passes through the opening, 26, in the plate, 23, to retain the window in the upper position. It is to be noted that, when when the window is supported in its closed position, the lifting strap is relieved of all strain. In fact the body of the strap is entirel free of the retaining means when the win ow is fastened in raised position. The fastening members on the other hand being carried directly from the-window and the window ledge are free of the body of the strap. A far more positive, much stronger and more flexible device results. Furthermore, the structure for retaining the window in its upper position is more or less flexible in nature, thereby permitting a yielding and sidewlse movement of the window, due to flexing or vibration of the body as it is driven.

The construction illustrated in the accompanying drawing and describediin this specification may be altered considerably, without departing from the spirit of my invention, and, therefore, I desire to claim my invention broadly, as indicated by the ap ended claims.

Iaving thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is:
